Description

Technical Field

[0001] This utility model relates to the field of tension control equipment, specifically a tension control device for cotton yarn twisting. Background Technology

[0002] Cotton yarn twisting is a process of winding silk into yarn. Cotton fibers are twisted together by a twisting device to become cotton yarn. During the twisting process, tension control equipment is needed to tighten the cotton yarn to help the cotton fibers twist together. Tension control equipment for cotton yarn twisting usually includes a drive motor and a take-up roller. The twisted cotton yarn is wound around the outer surface of the take-up roller, and the drive motor can be started to tighten the cotton yarn and take it up.

[0003] According to published patent 202321688436.5, a tension control device for cotton yarn twisting includes an outer frame. A drive motor is rotatably connected to the bottom of the outer frame, and the drive motor passes through the bottom of the outer frame. A vertical rod is rotatably connected to the top of the drive motor, and a take-up roller is fixedly connected to the outer surface of the vertical rod. In the process of realizing this utility model, the inventors found that at least the following problems remain unsolved in the prior art: the tension problem of cotton yarn is solved by setting a limit plate, a threaded rod, and a rotating handle. However, in use, although traditional tension control devices for cotton yarn twisting can control the tension of cotton yarn, they are cumbersome to install and cannot control the tension of two cotton yarns simultaneously. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a tension control device for cotton yarn twisting, so as to solve the technical problems that although the current tension control device for cotton yarn twisting can control the tension of cotton yarn, it is troublesome to install the cotton yarn and cannot control the tension of two cotton yarns at the same time.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a tension control device for cotton yarn twisting is designed, including a tension control mechanism. Both sides of the tension control mechanism are connected to first guide wheels through connecting shafts. A lead screw is connected to the middle of the tension control mechanism through a slot. The lead screw is connected to a second guide wheel through a slider. A servo motor is installed at the middle of the top of the tension control mechanism. First yarn guide plates are fixedly connected to both ends of the tension control mechanism. A second yarn guide plate is installed above the first yarn guide plate. A connecting plate is connected to the top of the second yarn guide plate through adjusting bolts.

[0006] Preferably, one end of the connecting shaft is rotatably connected inside the tension control mechanism, and the other end of the connecting shaft is fixedly connected to one end of the first guide wheel.

[0007] Preferably, the two ends of the lead screw are rotatably connected to the two ends inside the slot, the output end of the servo motor is fixedly connected to one end of the lead screw, and the mounting end of the servo motor is fixedly connected to the middle of the top of the tension control mechanism.

[0008] Preferably, the middle of the slider is connected to the outside of the lead screw via a thread, the outside of the slider is slidably connected to the inner wall of the slot, and one end of the second guide wheel is rotatably connected to the inside of the slider.

[0009] Preferably, the size of the first yarn guide plate matches the size of the second yarn guide plate, and semi-circular grooves are provided on both sides of the first yarn guide plate.

[0010] Preferably, one end of the connecting plate is fixedly connected to one end of the tension control mechanism, one end of the adjusting bolt is connected to the interior of the other end of the connecting plate via a thread, and the other end of the adjusting bolt is rotatably connected to the top of the second yarn guide plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model combines a connecting shaft, a first guide wheel, a slot, a lead screw, a slider, a second guide wheel, a servo motor, a first yarn guide plate, a second yarn guide plate, an adjusting bolt, and a connecting plate. When the cotton yarn tension is controlled, the cotton yarn first passes through the semi-circular groove of the first yarn guide plate, then passes above the two first guide wheels and below the second guide wheel. Then, the adjusting bolt is rotated, which causes the second yarn guide plate to move downward, thereby making the second yarn guide plate coincide with the first yarn guide plate. This achieves the limitation of both ends of the cotton yarn and improves the convenience of cotton yarn installation.

[0013] When controlling the cotton yarn tension, the servo motor can drive the lead screw to rotate clockwise, causing the lead screw to move the slider downwards within the slot. This allows the second guide wheel to adjust the cotton yarn tension, enabling simultaneous tension control of the cotton yarn on both sides of the tension control mechanism, thus improving the convenience of the tension control equipment in controlling the cotton yarn tension.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0019] Example 1: A tension control device for cotton yarn twisting, see [link to example]. Figures 1 to 3 The tension control mechanism includes a tension control mechanism 1. Both sides of the tension control mechanism 1 are connected to first guide wheels 12 via connecting shafts 11. One end of the connecting shaft 11 is rotatably connected inside the tension control mechanism 1, and the other end is fixedly connected to one end of the first guide wheel 12. A lead screw 14 is connected to the middle of the tension control mechanism 1 via a slot 13. The lead screw 14 is connected to a second guide wheel 16 via a slider 15. A servo motor 17 is installed at the middle of the top of the tension control mechanism 1. The two ends of the lead screw 14 are rotatably connected to the two ends inside the slot 13. The output end of 17 is fixedly connected to one end of the lead screw 14, and the mounting end of the servo motor 17 is fixedly connected to the middle of the top of the tension control mechanism 1. When the cotton yarn tension is controlled, the servo motor 17 can directly drive the lead screw 14 to rotate clockwise, so that the lead screw 14 drives the slider 15 to move downward in the slot 13, thereby allowing the second guide wheel 16 to adjust the cotton yarn tension. This enables the tension of the cotton yarn on both sides of the tension control mechanism 1 to be controlled simultaneously, improving the convenience of the tension control device in controlling the tension of the cotton yarn.

[0020] The tension control mechanism 1 has a first yarn guide plate 18 fixedly connected to both ends. A second yarn guide plate 19 is installed above the first yarn guide plate 18. A connecting plate 21 is connected to the top of the second yarn guide plate 19 via an adjusting bolt 20. The middle of the slider 15 is connected to the outside of the lead screw 14 via a thread. The outside of the slider 15 is slidably connected to the inner wall of the slot 13. One end of the second guide wheel 16 is rotatably connected to the inside of the slider 15. The size of the first yarn guide plate 18 matches the size of the second yarn guide plate 19, and semi-circular grooves are provided on both sides of it. One end of the connecting plate 21 is fixedly connected to one end of the tension control mechanism 1. One end of the adjusting bolt 20 is connected to the inside of the other end of the connecting plate 21 via a thread, and the other end of the adjusting bolt 20 is rotatably connected to the top of the second yarn guide plate 19. When the cotton yarn tension is controlled, the cotton yarn is first passed through the semi-circular groove of the first yarn guide plate 18, then passed above the two first guide wheels 12 and below the second guide wheel 16, and then the adjusting bolt 20 is rotated. The adjusting bolt 20 will drive the second yarn guide plate 19 to move downward, so that the second yarn guide plate 19 coincides with the first yarn guide plate 18, thereby limiting the two ends of the cotton yarn and improving the convenience of cotton yarn installation.
